I have a 4x5 graflarger that came with a stand to convert the camera to an enlarger. I don't see any marking on the stand to tell who the manufactor was. It has a grey baseboard about 15x17" with a riser that comes apart in two pieces. The base of the riser is triangular in shape. The complete riser is about 36" tall. There is a sliding bracket the both raises, lowers, and moves the camera in/out from the riser. I wonder if this is a Graflex part or universal?

If memory serves me right, the graflex stand had a mere decal on the triangle base. They used this same base for their real enlarger (looked like a federal). Adorama used this same style stand for their copy stand they sold through the 70s.

I found an old master studio camera that is manufactured by graflex. The stand has the same decal on it and it also says master studio stand by graflex. I have been doing research to find what year it is. It is a "sliding stand" anyone with some help I would appreciate it. My father passed away a month ago and i was always told this was an antique.

I can't say that I'm up on a "sliding stand" by that name. Most of the Century portrait cameras had or could come with a sliding carriage that would give two pictures on either 8x10 or 5x7 depending on the model.
The stands for a large portrait camera would say something like "Semi-Centenial Stand" or "Century 3a stand"

For a rough date look at who made it.
The company we loosely refer to as Graflex went through several name changes over the years.
